Abstract:

With the rapid expansion of industry, urbanization and increasing population in Thailand, many cities face the problem of municipal solid waste (MSW) disposal. The great majority of a plant for MSW, which are in operation around the world, are based on mass burn incineration systems. There are, however, a number of novel, thermal processing technologies for MSW, based on pyrolysis and/or gasification of the waste, which may provide significant technical and environmental advantages over conventional incineration. The objective of this article is to investigate the effect of operational parameters to electricity produced efficiency. The processes consist of drying unit, thermal waste treatment unit which is comprised of pyrolysis, gasification and combustion units, heat recovery steam generation unit, power generation unit and gas cleaning unit. The article are applied to the performance analysis of a MSW power plant in case of after passing through drying unit pyrolysis unit was operated at constant MSW feed rate of 28 tonnes/hr with varied moisture content. At lower moisture content which led higher energy content and more excess air required, the efficiencies of system were increased.
